IMPROVEMENT IN ORGAN-STOP KNOBS.

Specification forming part of Letters Patent No. 164,518, dated June 15,1875; application filed May 17, 1875.

- To all whom it may concern:

Be it known that I, RILEY BURDETT, of Erie, in the conntyof Erie andState of Pennsylvania, have invented an Improvement in Organ-Stop Knobs,of which the following is a specification:

The object of this invention is the production of an organstop knobwhich shall be legible, durable, and ornamental.

This invention is illustrated in the accompanyin g drawing as follows:

Figure 1 is a transverse sectional view thereof. Fig. 2 is afront view,and Fig. 3-is a view of the backing, of the stop-scalp and the rimconnecting it therewith.

A indicates the recessed stop-rod, registerhandle, or knob. B indicatesthe porcelain name-plate or scalp. 0 indicates the metal or other rim orbeading connecting the scalp with its paper, pasteboard, or otherbacking D. I secure the scalp in its place in the knob A by gluing itsbacking D therein.

Porcelain-scalped knobs have, for some time, superseded those made withivory scalps, because the former do not discolor, and are general] ymore legible and ornamental. But their use has been hindered by theinability of their makers to attach them, as ordinarily constructed, sofirmly to the knobs as to render them permanent. Consequently, fineorgans in which the ordinary porcelain-scalped knobs are used have oftenbeen condemned by the buyer, owing to the falling out of the scalps,causing him to conclude that the whole organs were poorly made.

It may be proper to state further in this connection that organ-makershave been obliged, until quite recently, to order porcelain scalps fromFrance, and, therefore, have, when doing so, ordered French knobstherewith; yet the insecure connection of scalp and knob by the Frenchmethod of attaching the porcelain with glue directly to the wood,without rim or back ing, has rendered these stop-knobs almost useless inour climate.

In my device I obviate this objection wholly by employing a metal orother rim or beadin g for the porcelain scalp, and a paper or othersuitable backing, this rim connecting the scalp and backing, and thebacking being attached to the stop-knob with glue, thus combining theseseveral parts so securely as to render their separation, in the use ortransportation of an organ in which they are employed, impossible.

I claim- In combination with the recessed stop-rod, register-handle, orknob, A, the porcelain nameplate or scalp B, provided with a paper,pasteboard, or other suitable backing, D, and the metal rim or beading(l, substantially as described, and for the purpose set forth.

RILEY BURDETT.
